Multiple public web sites can be used to obtain ship-related information that is relevant to Maritime Domain Awareness (MDA). However, the quality or timeliness of this information can be suspect. In this paper, a software application, called the consistency application, is presented for the comparison of ship-related information from multiple data sources. The consistency application allows a user to compare the information from these multiple data sources and generate a comparison score for the specific ship information supplied by the data source, and also for the data source as a unit. This allows the user to assess the consistency of the information provided from the data source, as compared to other sources. The consistency application presently links four MDA-related information sources.
